Abstract
Techniques for detecting a predetermined waveform pattern in a signal received at a system are disclosed herein. A standard deviation and an average of the signal are calculated and used to determine a plurality of zones for the signal. A plurality of samples is obtained from the signal and one of the zones is associated with each of the samples. Transitions of the signal between the zones are identified based on the association of the zones with the samples. A predetermined waveform pattern may be detected in the signal based on the transitions between the zones. A notification may be generated indicating that the predetermined waveform pattern is detected based on a correspondence of the transitions of the signal matching a set of the predetermined transitions.
